Use the meson macros in talkatu.spec.in rather than running it manually.
Testing Done:
Successfully ran the build for `fedora-31-amd64` and `fedora-32-amd64` but `fedora-33-amd64` and `fedora-rawhide-amd64` are failing with the `c compiler can't build executables` error I'm still working on figuring out.
